🇪🇺 #ESA 📆 2023 Annual #SpaceEnvironment Report : Over 80 % 📈 of constellation #satellites 🛰️ launched in 2022 were inserted into #orbits from which they will decay towards #Earth in less than two years 📉 once they are no longer operational or if they lose propulsion. The increasing number of satellites reentering Earth’s atmosphere is therefore expected to continue in coming years. For older pieces of debris, the only solution is active #SpaceDebrisRemoval. https://www.esa.int/Space_Safety/ESA_s_Space_Environment_Report_2023

If I wasn't fully disabled, I'd apply. #PHA #NEO are stuff I'm interested in. Last time I calculated orbits was when I was still a teen, 4 decades ago. It's been nearly as long since I programmed in #FORTRAN.

#Orbital motion - there are exotic possibilities such as knife-edge #orbits, in which the #satellite can be made to execute an arbitrarily large number of nearly circular orbits, after which it flies back outward. https://en.wikipedia.org/wiki/Schwarzschild_metric#Orbital_motion
In #Einstein's theory of general #relativity, the #Schwarzschild solution is an exact solution to the Einstein field equations that describes the #gravitational field outside a spherical mass

A #photograph of a United Launch Alliance #ULA #AtlasV #rocket, in its 401 configuration, ascending into the blue #Florida sky.
This Atlas V, with its 4 meter fairing, no solid rocket boosters, and a single #RL10 #engine on this #Centaur upper stage, is carrying a #Quasar #comsat for the National Reconnaissance Office #NRO. Quasar is believed to be the name for a network of communication #satellites that allow the NRO to maintain constant contact with its #spysats and #downlink data and #uplink tasks continuously.
The system has satellites in both #geostationary and #Molniya #orbits.

Every few months or so I have to draw out the difference between eccentric, mean and true anomalies for Keplerian orbits. I've been working in this field for almost twenty years, you'd think I'd know it by now.... #astrodon #orbits #exoplanets
The moon begins to wane, the sun begins to rise. No two morning walks the same, each in our new disguise?

Found this last night, and still thinking about it. 🤯
Science fiction writer, Arthur C. Clarke (of 2001: A Space Odessy fame) happens to also be the father of the Geostationary Orbit - where we put our weather satellites ... a distance and velocity that keeps them located over a point on Earth with a 24 hour orbital period.
Also - casually mentions re-usability of rockets and using solar panels for power generation ... years ahead of its time!

I had what felt like a very profound time lying looking up at the moon in the bright blue sky this afternoon. I got to #pondering why it changes shape, being a slither at the moment 🌘.
Then I started thinking about the sun's path across the sky and actually how it's us turning🌏 🤯
I get lunar phases🌒🌕🌔, I get seasons and solstice and I still get wowed at the whole shebang!
